Application led March 30,1921. Serial No. 456,819.

To all 'whom t may concern:

.Be it known that I, THOMAS Coscnovn, Jr., a citizen of the United States, residing at Canton, in the county of Starkand State of Ohio, have invented a new and useful Disk Valve, of which the following is a specification.

This invention relates to valves and more particularly to a quick opening and closing disk valve especially adaptable for use in a uid line and arranged to-be operated from i the exterior of the valve casing.

The objects of the invention are to pro-` vide a valve of' the disk type which will permit of quick and easy operation of the valve from the exterior and in which suitable packing is provided to prevent leakage 'i around the valve stem; to provide a valve of this character comprising a plurality 0f disks connected to av singlewalve stem and arranged to be simultaneously operated in conjunction with separate valve seats, each valve disk and seat heilig provided with an annular lip or flange to assureproper seating of the disks and to automatically clean the engaging surfaces of the disks. and valve seats bythe opening and closing movement ofthe Valve; means being provided for ad- .justing the compression upon the valve to cause the same to properly seat upon the valve seats when moved to the closed position; other objects being to generally simp-lify and improve the construction of Valves of this type. A p

The above and other objects may be attained by providing avalve casing havin a partition wall therethrough, three s acecgl ports being 'provided in said wall an surrounded by annular lips or flanges forming valve seats, similar lipsor flanges being-provided between said ports, all of the valve seats thus provided being located in a circle, thevvalve stem being located through a suitable 'stufling box in the casing and being concentric with said valve seats and having a head mounted upon its inner extremity as by a ball and socket connection, said head having three disks thereon, each provided with an annular lip or flange arranged to be normally seated upon one of the valve seats, spring means being provided for urging the valve head normally toward the' valve seats, means being provided upon the exterior of the casing for rotating the valve stem and head in order to move the d1sks into engagement with thel valve seats surrounding the ports or into engagement with the seats located between the ports.

With these objects in View, the invention consists in the construction and arrangement of parts hereinafter described, and illustrated in the accompanying drawing, it being understood that changes in the pro-portion and details of construction may be made within the scope of the appended claims.

The invention thus set forth in general terms is illustrated in the accompanying drawings, in which Figure 1 is a plan view of a valve embodying the invention;

Fig. 7, a plan view of the same.

Similar numerals of reference indicate ,corresponding arts throughout the several igres of the rawing.

eferrin first to the constructionillustrated in igs. 1 to 4 inclusive, the valve casing is preferably cylindrical in shape as indicated at 1, an provided with the inlet and outlet necks 2 and respectively, 1ocated at'opmsite sides'of the casing, a partition wall 4 bein located through the interior of the casing and dividing the same intothe inlet chamber 5 and outlet chamber 6 communicating with the necks 2 and 3 respectively.'v y

The wall 4 is provided with spaced ports 7, located in a concentric circle, an upwardly disposed annular flange 8 being provided `around each of said ports forming a valve seat. Similar annular flanges 9 are located between the valve seats thus formed, there being no opening, however, within each of these flanges.

The cover plate 10 of the valve casing may be connected to the annular flangell of the casing as by the bolts 12 or the like located through registering slots 13 and 14 in the flange and cover plate respectively.

A concentric, depending stuffing box 15 is formed integral with the cover plate and the upwardly disposed arch or yoke 16 is preferably formed' thereon above said stulling The valve stem 17 is journaled through the threaded bushing 18 which engages internal threads 19 in the arch or yoke 16, a coil spring 20 being interposed between the lower end of said bushingl `and the thimble 21 which is slidably and rotatably mounted upon the lvalve stem and provided with a clearance. The semi-spherical portion 22 upon said .thimble is received in the lsocket 23 of the collar 24 which is fixed upon the valve stem as by the pin 25.\

The valve stem extends through the stuifing box, the bushing 26 being located around the valve stem andheld within the stuffing box to compress the packing 27, by means of the bolts 28. The threaded bushing 18 vis provided with a hexagonal portion 29 for the rece tion of a wrench or other tool, in 'ordgr t at the bushing may be adjusted to place the proper tension upon the spring 20, and the operating handle 30 is stem x17 for rotating the same.

The lower end ofthe valve stem is provided with a ball ortion 31 which engages theA socket 32 in t e valve head, indicated generallyv at A shank having one or more flat sides such as shown at 34 is pro+ v1ded upon `the valve stem for engagement @with the similar shaped aperture 35 in the valve head, in order that the head ma -be flng the passage of fluid fromthe inlet chamber 5 to the outlet chamber 6. t When 1t is desired to open the valve, the

handle 30 is turned, turning the valve head through the stem` until the disks u37 are I into engagement with the annular` flanges 9, the .flanges 38 of the disks resting` mOVB upon the flanges 9.

The spring vpressure suiclent l to hold the anges of the valve dlsks 1n tight engagement with the flanges 8 or 9- and as three equally spaced disks areprovlded, the ball. and socket connections be tween' the valfvehead and the stemcauses 'the' pressure to be .'evenly distributed, causin each valve disk to seat solidly u on the jacent valve seatl8lor annular ange 9,' de'-J pending upon the position of the valve.

provided upon the upper end of the valve rotated with the valve stem, a sli ht c ear` on the valve/head isJ imanes form of the invention, all ofthe parts being the same as shown in Figs. 1 to 4 inclusive with the exception of themeans for groducing pressu e upon the valvestem. "n this form `of the invention a pa1r of U-shaped s ring armsl 40 arel connected to the cover p ate as by the bolts 41, the upper ends thereof being connected together by a plate 42 attached to each spring as by the bolts 43. The

threaded bushing 18a is located through the plate 42 and engages the half round thimble 22a which is recelved Within the socket 2 33I formed in the collar 24". In Figs. 6 and 7 isl illustrated ar slightly modified form of the valve proper in which the. head 33a is connected to the stem 17in the usual manner, each disk 37a being separate and provided with a ball portion 44 which is received-in the socket. 45 in the'. j

valve head. With this form of valve the danger of the disks Inot seating squarely is reduced -to aminimum, as each disk is movable within the adjacent socketv of the valve head independently of the other disks.

It will be evident from the above4 and the accdmpanying drawi-ngs that a valve is provided which may be quickly and easily operated to move the valve to the full open or full closed position in a single quick move"-v ment. The valve disks being providedwith the annular flanges arranged to seat upon the annular` valve seats 8 when in the closed position, and upon the annular flanges 9- when in the open position, permits each disk to fit tightly upon its seat and allows any dirt or foreign matter which may be deposited upon the valve seat or the surface of the disk to be wiped therefrom and deposited i within the lannular flange 9 or within the port 7 as 'the valve is moved, thus preventing foreign matter from causing any dif- ,y

iculty in the seating of the valve.

A valve including a rcasing provided with inlet and outlet openings,- a partition dividing the casing 1into inlet and\\outlet chambers, said partition havin ports therein, arotatable valveuhead, disks upon said head arranged to seat over said ports and a\ valve stem extending through the casing and connected to the"va1ve head by a ball and/(socket joint.
